How to set default coordinates if access to geodata is denied in Yandex API?

Question

Yandex maps

If access to geodata is denied, the center is set by the provider, but you need to set the center that you specified when creating the map.

Tell me how to do it?

My code

if (document.getElementById('map')) {
    fetch('./addresses.json')
    .then(response => response.json())
    .then((adresses) => {

        ymaps.ready(function () {

            let imgUrl = './img/dist/icons/'; // путь к иконкам меток

            ymaps.geolocation.get().then(function (result) {

                result.geoObjects.options.set(label('label-user')) // Определяем метку пользователя

                // Создаём карту
                let myMap = new ymaps.Map('map', {
                    center: [ 51.128207, 71.430411 ],
                    zoom: 10,
                    controls: [ 'routeButtonControl', 'geolocationControl', 'zoomControl', 'routeButtonControl' ]
                });

                // Стили меток
                function label(label) {
                    return {
                        iconLayout: "default#imageWithContent",
                        iconImageHref: `${imgUrl}${ label }.svg`,
                        iconImageSize: [ 23, 30 ],
                        iconImageOffset: [ -5, -38 ]
                    }
                }

                // Содержимое Balloon
                function balloonContent(item) {
                    return `<div class='balloon-content'>
                                   ...
                                </div>`
                }

                // Метки сluster
                let myGeoObjects = [];
                for (let item of adresses) {
                    myGeoObjects[item.id] = new ymaps.GeoObject({
                        geometry: {
                            type: "Point",
                            coordinates: [ item.lat, item.long ]
                        },
                        properties: {
                            clusterCaption: `${ item.title }`, // Description (Optional. If clusterDisableClickZoom: true),
                            balloonContentBody: balloonContent(item),
                        },
                    }, item.point <= 3 ? label('label-red') : label('label'));
                }

                // Стили сluster
                let myClusterer = new ymaps.Clusterer({

                map.addEventListener('click', ({ target }) => {

Resolved the next issue. way:

...
             // Render -----------------------------
                function defineLocationCoordinates() {
                    myMap.setCenter(result.geoObjects.get(0).geometry.getCoordinates(), 10, { duration: 100 });
                }

                function defineDefaultCoordinates() {
                    myMap.setCenter( [ 51.128207, 71.430411 ], 10);
                }

                if (!navigator.geolocation) {
